#30DayMapChallenge 2023
Jasmine Siyu Wu
10/18/2023
You will be participating in the 30-day mapping challenge! For this class, you will be required to submit a map for at least 10 of the days above. Your map should be posted to your GitHub Repo on the corresponding day and if you have an account, post on social media with the hashtag #30DayMapChallenge and tag the MUSA program also of course!
If you just post 10 maps on the last day, I won’t be happy. Feel free to plan ahead. The map doesn’t have to be perfect but try to use our data visualization design principles. You can use any mapping package.
Please organize your repo so that it also includes a Folder for the outputs and save each map as a file (png or jpeg). Document your R markdown. Make that pretty - also.

Data sources:
All the Airports Across The World Dataset
IATA stands for the International Air Transport Association. It is a global trade association representing airlines and the air transport industry. IATA’s main objective is to promote safe, reliable, and efficient air transportation. It establishes industry standards, provides training and support services, and advocates for the interests of its member airlines. IATA also develops and maintains industry codes, such as airline and airport codes, to ensure uniformity and efficiency in air travel operations worldwide.
ICAO stands for the International Civil Aviation Organization. It is a specialized agency of the United Nations responsible for setting international standards and regulations in the field of civil aviation. ICAO’s primary goal is to promote the safe, secure, and orderly development of international civil aviation. It establishes standards and procedures for aviation safety, security, efficiency, and environmental protection. ICAO also facilitates cooperation among member states and provides technical assistance and training to help improve aviation capabilities worldwide. Additionally, it serves as a forum for member states to address common aviation issues and work towards harmonization of regulations and practices.
Altitude refers to the vertical distance above a reference point or a specific surface, such as sea level. It is commonly used in aviation and geography to indicate the height or elevation of an object or location above the Earth’s surface. Altitude is measured in units such as feet or meters. In aviation, altitude plays a crucial role in determining the aircraft’s position in relation to the ground or other aircraft, as well as in planning flight routes and complying with airspace regulations. In geography, altitude is used to describe the height of mountains, hills, or other landforms, and it affects factors like climate, vegetation, and atmospheric conditions.

This map uses OpenStreetMap data, including features of motorway, primary, secondary, tertiary, residential, living street, unclassified, service, and footway.
Note: Since the data is too large to load when knitting the RMarkdown, I mute the code and directly read in the saved plot.
